对于繁重的计算，Fortran 比 c 更容易优化吗？

Question

From time to time I read that Fortran is or can be faster then C for heavy calculations. Is that really true? I must admit that I hardly know Fortran, but the Fortran code I have seen so far did not show that the language has features that C doesn't have.

If it is true, please tell me why. Please don't tell me what languages or libs are good for number crunching, I don't intend to write an app or lib to do that, I'm just curious.

Answer 1

Any speed differences between Fortran and C will be more a function of compiler optimizations and the underlying math library used by the particular compiler. There is nothing intrinsic to Fortran that would make it faster than C.

Anyway, a good programmer can write Fortran in any language.
